Data Visualization using Speedometer Graph

This is an Example to Visualize data with Speedometer Graph in React Native using react-native-speedometer. We all have seen the speedometer in the vehicle which shows the speed of the vehicle. It is always really cool to visualize a continuous changing data in the speedometer as it shows the current state in a very effective way which is easy to understand. In the React Native, we can make the same Speedometer type graph to show different data or you can also use it as a loader for any progress.

This library provides lots of props to customize which can be seen here.

In this example, we will make a Speedometer graph by setting custom labels, label color, and active bar color. There will be an input on the screen to enter the value and this value will change the speedometer.

To Make a React Native App

Getting started with React Native will help you to know more about the way you can make a React Native project. We are going to use react-native init to make our React Native App. Assuming that you have node installed, you can use npm to install the react-native-cli command line utility. Open the terminal and go to the workspace and run

npm install -g react-native-cli

Run the following commands to create a new React Native project

react-native init ProjectName

If you want to start a new project with a specific React Native version, you can use the --version argument:

react-native init ProjectName --version X.XX.X

react-native init ProjectName --version react-native@next

This will make a project structure with an index file named App.js in your project directory.

Installation of Dependency

To use RNSpeedometer we need to install react-native-speedometer dependency.

To install this open the terminal and jump into your project using

cd ProjectName

Run the following command to install

npm install react-native-speedometer --save

This command will copy all the dependency into your node_module directory.

Code for Speedometer Graph

Now Open App.js in any code editor and replace the code with the following code

To Run the React Native App

To run the project on an Android Virtual Device or on real debugging device

react-native run-android

or on the iOS Simulator by running

react-native run-ios (macOS only).
